Slate is a more homogeneous material than marble - Marble gets its patterns from other materials, such as sand, Iron Oxide, Chert and the like - this breaks up the material such that it has boundaries within the cut slab/pieces. While slate can have occlusions - typically its value is in homogeneity where as Marble's value is in the 'movement' the patterns of impurities.
-It should also be recognized that Marble covers a wide range of materials from calcite and dolomite to metamorphosed limestone.
Other than water jet cutting- Slate can be cut with diamond tools and copious amounts of water - it is also relatively soft, so can be polished/honed with Aluminum Oxide (AlOx, Al2O3) or Silicon Carbide (carborundum(r) SiC)
